“…38,47 in one series, only 1 case out of 49 patients presenting with refluxing units treated by initial endoscopic puncture and subse quent endoscopic treatment of vur required ureteric implantation. 48 Kajbafzadeh et al 43 even proposed a pre emptive endoscopic treatment of all ureters that showed signs of reflux on the micturating cysto urethrography performed before endoscopic decompression, and reported a secondary surgery rate of 10% after 4.2 years' followup.…”

Ureteroceles associated with the upper pole of a complete ureteral duplication are known as duplex system ureteroceles (DSUs). A limited knowledge of the natural history of this condition makes its management in neonates and infants controversial. Asymptomatic neonates diagnosed antenatally in the absence of severe hydroureteronephrosis (HUN) are at low risk of developing urinary tract infections during the first months of life. These patients might, therefore, begin antibiotic prophylaxis and undergo comprehensive assessment by 3-6 months. Subsequently, conservative management can be viable in patients without severe HUN or high-grade vesicoureteral reflux (VUR). Cases of DSUs with severe HUN but no VUR can be treated by an upper urinary tract approach or by endoscopic decompression depending on upper pole function. Patients with preoperative VUR represent the most challenging cases. If VUR cure is considered necessary, lower urinary tract reconstruction is recommended. Endoscopic decompression allows for a definitive treatment in at least 50% of cases and, in the remaining cases, can be combined with conservative management or endoscopic treatment of VUR. Nonfunctioning or poorly functioning upper poles can be left in situ both in lower urinary tract reconstruction and after endoscopic decompression. Parental preferences should also be taken into account in the decision-making process.

“…Several techniques for endoscopic ureterocele decompression in children have been previously used, including incision with electrocautery, cold knife incision, puncture with a stylet [3,4,8,10]. Regardless the technique used, the only encountered and described complication, was new-onset Vesicoureteral Reflux (VUR) into the punctured system.…”

“…Regardless the technique used, the only encountered and described complication, was new-onset Vesicoureteral Reflux (VUR) into the punctured system. Reported rates of postoperative VUR ranged from 18 to 27% [1][2][3][4]6,8] one have to be very careful using new techniques for endoscopic treatment and have to take into consideration that possible complications may overweight the advantages.…”

“…Endoscopic puncture/incision is currently suggested as the first line treatment for ureteroceles, especially those associated with single system and intravesical ureteroceles. The timing of endoscopic intervention toward earlier periods has been noted [1][2][3][4][5][6][7][8]. Recently transurethral laser incision of ureterocele has been proposed as a safe and efficacious option [9][10][11].…”

Endoscopic decompression has been recently suggested as the first line treatment of ureterocele in children, including laser transurethral incision. We report a case of a unique but very serious complication after simple ureterocele puncture using a holmium laser in an infant. A 6-week-old male with a history of laser treatment of right simple ureterocele (procedure performed at the other institution 2 days earlier) was admitted because of sepsis. Imaging studies revealed urine leak around the bladder. Destroyed right bladder wall with perforation (locally coagulated and buried tissue) and damaged distal part of the right ureter along the distance of 3-4 cm were found during cystoscopy and laparotomy. Bladder was closed wall after removal of damaged tissues and then end right ureterocutaneostomy was done. The presented case shows that one has to be very careful using new techniques for endoscopic treatment, especially in very young patients and complications may overweight the advantages. KeywordsUreterocele, Laser therapy, Endoscopic incision, Children Case ReportA 6-week-old male after laser incision of a simple right ureterocele performed at the other hospital two days before admission to our institution, was admitted because of general bad condition and signs and symptoms of sepsis. Endoscopic incision was done as an outpatient procedure and a boy was discharged home immediately after cystoscopy.Ultrasound (US) showed mild distention of the right collecting system and upper part of the right ureter CASE REPORT

“…Endoscopic puncture is the most common method, whereby an electrode or laser is used to create one or more small incisions and relieve obstruction of urinary flow. 5,6 While this technique is less invasive than open repair, instrumentation may seed bacteria into the urine and lead to a UTI. Furthermore, there are concerns regarding the use of general anesthesia in children, especially neonates.…”

Purpose: To evaluate the feasibility of performing noninvasive puncture of pediatric ureteroceles with cavitation-based focused ultrasound (US) (histotripsy). Materials and Methods: A model for the ureterocele wall was developed from an excised bovine bladder wall. The model was exposed to focused US pulses in a water bath under three different US parameter sets for up to 300 seconds to create localized perforations in the wall. B-mode US imaging was used to monitor the treatment and assess potential imaging guidance and feedback. Results: Punctures were formed between 46-300 seconds, depending on the focused US exposure parameters and model wall thickness. Puncture diameter was controllable through choice of exposure parameters and could be varied between 0.8-2.8 mm mean diameter. US-induced cavitation was visible on B-mode imaging, which provided targeting and treatment feedback. Conclusions: Cavitation-based focused US can create punctures in a model that mimics the tissue properties of a ureterocele wall, under guidance from US imaging.
